Gibbed's save editor for Borderlands! Almost easy to use and yes... enjoy!
This save editor can edit weapons like add scope or change barrel and change their quality! Can also change your character and add credits and everything!!1

I have downloaded the file and unzipped it, but i can't run it?....I have xp pro and i get "The application failed to initialize properly (0xc8888135). Click on OK to terminate the application."...can anyone help me? ...Do I have to have a steam account for this to run?....I am lost...please help

willow tree... thats all im saying. you will never need another save editor for borderlands again. it literally has everything. ever custom weapon making. but thats probably the hardest part... willow tree, it can do anything (almost.. you can't put roland head on lilith for example.. that would just be silly..)

EDIT: i do not know if it works with steam version but it should as long as ou know where the save files are.
and im pretty shure it does not work for xbox360 or ps3
